To make things easier for outline rendering, load the available project over your project without replace. This adds a material and post effect. Apply the material "SetIdentifier" to any SDS or NURBS objects you have. Then open up the object's Properties window and in the "Surface Properties" panel at the top, change the attribute from "Color" to "id". You can use this to set the identifer and can use values larger than 0.0-1.0. The value doesn't matter as long as it's unique. Two objects with the same id number won't have edges rendered where they overlap.
